CHICAGO, ILLINOIS AUTOMATIC MOPPADMAKING MACHINE Application led August18, 1924. Serial No. 732,657.

This invention relates to the manufacture of mop heads.

One of the principal objects of the invention is to provide means forproducing bundles of yarn of the requisite length and number for a mophead.

Another object of the invention is to pro' vide means for automaticallymeasuring, binding and cutting the yarn.

Other and further important objects of this invention will be apparentfrom the disclosures in the accompanying specification and drawings.

The invention (in a preferred form) is illustrated in the drawlngs andhereinafter more fully described. v

As shown on the drawings:

The machine comprises a bobbin-head 15 revolubly mounted in a frame 16.This hobbin-head has a hollow center through which pass two pairs ofendless cables 17. These cables are supported by a series of guidepulleys 18 and driving pulleys 19. The bobbin- Figure 9 is a sideelevational detail showing head revolving around these cables wraps yarntherearound and the coiled yarn so formed is carried by the cablesbetween two tape rolls 2O and 21. These rolls feed tape 22 onto eachside of the coils of yarn and the whole passes over the platform 23 of asewing machine 24 which sews the two ta es together with the yarntherebetween. he coils of yarn then pass over a revolving tape cutter 25which is mounted on a carriage having an elliptical movement lengthwiseof the machine such that when the carriage is in the upper part of itsmovement it is travelling in the same direction and at substantially thesame speed as the cables. At this time the cutter 25 is raised highenough to sever both tapes. The cutter then drops and returns to itsoriginal position to Sever the tapes at another point.

The next step is to sever the yarn adjacent the ends of the loops. Forthis purpose horizontal revolving cutters 26 are provided which enterthe space between each pair of cables 17 as shown more particularly inFigures 1, 2, 10 and 11. The mop sections are then free to drop from thecables 17 onto a belt conveyor 27 arranged therebeneath.

As best shown in Figures 3 and 4 the bobbinhead 15 comprises two drumheads 28 having driving gears 29 attached thereto for engagement withgears 30 upon the main driving shaft 31. vOn each drum head is a flange32 between which flanges pass shafts 33 on which bobbins 34 arerotatably mounted. These bobbins carry the yarn which goes to form themop head.

The bobbinvhead revolving about the cables 17 coils the yarn about thelatter and these coils are then carried between the tape wheels 20 and21. As best shown in Figure these tape wheels are rotatably supported bya pair of uprights 35 having slots therein for the reception of the axlepins of the wheels. The tapes feed from the two rolls between a pair ofrollers 87, positioned against the upper and under sides of the yarncoils, respectively.

The coils with tape arranged beneath and above pass over a table 23 andunder the sewing machine 24 driven from the shaft 31 by gears 36, 37,shaft 38, gears 39, 40 and Cri shaft 41 where the tapes are stitchedtogether tlius fastening the yarn to the tapes.

The cutter 25 as best shown in Figures 6 to 9, inclusive, consists of acircular disc driven through suitable gearing 42 by an electric motor43. This-motor is mounted on a platform 44 pivotally connected at oneend at-45 to sleeves 46 which slide upon a pair of guide rods 47 carriedby the main frame. Adjacent the point 45 are two lugs 48 depending fromthe platform 44 for pivotal engagement with a link 49. The other end ofthe link 49 is attached to a second link 50 which in turn is attached at51 to the connecting rod 52 of an eccentric slieave 53 operated by aneccentric on a shaft 54. This shaft is rotated from a shaft 84 by wormwheel 55 and worm 56; this shaft 84 being in turn driven from the maindriving shaft 31 by gears 85 .and 86. By means of this eccentric and thelink connections referred to the carriage 44 which carries the cutter25is oscillated to and fro.

To provide means for adjusting the range and speed of oscillation of thecarriage 44 the lower end of the link 50 passes through a block57pivotally mounted in a block 58 slidably arranged on a pair of guiderods 59. The block 58 may be clamped on the rods. 59 in any desiredposition and similarly the link 50 may be clamped in adjusted positionwithin the block 57.

In addition to moving the cutter to and fro, it is also raised andlowered to bring it into and out of engagement with the tapes to be cut.The path of movement is therefore roughly elliptical with the cutterrising, moving forward at the same speed as the tapes on the upper partof the path, then dropping and returning. For raising and lowering thecutter, a downwardly projecting arm 60 is arranged on the carriage 44.The lower end of this arm is forked and straddles a frame 62 verticallyslidable on a pair of guides 63. Between the forked ends of the arm 60is a roller 61 adapted to travel in a slot 64 in the upper part of theframe 62. This allows the carriage 44 to oscillate freely to and fro.The frame 62 and the cutter end of the carriage 44 are oscillated up anddown by an eccentric 65 on the shaft 54 connected to the frame 62 bysheave 66 and rod 67 (Figure 9). The carriage 44 pivots about the point45 during this up and down oscillatory motion.

The cutter 25 serves the tapes at the required intervals and the nextoperation consists in cutting the coils of yarn at their ends.

This is accomplished by circular cutters 26 (shown in Figures 10 and 11)which are supported by brackets 68 and driven by gears 69 and 70 from ashaft 71. This shaft is driven from a cross shaft 7 2by grooved pulleys73, 74 and belt 75.

As the ends of the coils are cut the sections drop onto a conveyor belt27 which passes around a pulley 76 on the shaft 72.

This shaft 72 is driven from a shaft 77 by means of a chain and sprocketwheels 78, 79. On the shaft 77 is arranged a worm wheel 80 engaged by aworm 81 on the main driving shaft 3l.

The shaft 77 also operates through gears 82 and 83 the driving pulleys19 for the cables l The operation of the mop machine is showndiagrammatically in stages b Figures 8, 5 and 12. The yarn is wound bythe bobbins around the four central strands of the cables 17, themovements of the bobbins and cables being synchronized to give closelyand evenly wound coils. As the coils of yarn pass be-A tween the tapefeed rollers 87, tapes 22 are laid against the upper and lower sides ofthe coils. The tape next passes over a table 23 and under the foot of asewing machine 24, which sews the two ta es together with the yarn coilsbetween. T e tapes are next severed by the rotary cutter 25, as shown at88 on Figure 12, and Athen the yarn is cut at the looped ends 89 of thecoils by a pair of stationary cutters 26, positioned on each side of theyarn coils between the upper and lower strands of the cables 17. Thelength of mop, or swatch, when severed from the cables 17, falls down ona belt conveyor 27, traveling at the same speed as the cables. Thisswatch is now ready to be formed into a mop head and attached to a mophandle in any suitable manner.

I am aware that numerous details of con struction may be varied througha wide range without departing from the principles of this invention,and I therefore do not purpose limiting the patent granted otherwisethan necessitated by the prior art.
